Abstract

The Canadian Forest Fire Weather Index (FWI) system was evaluated for the Daxing'anling region of northern China for the 1987-2006 fire seasons. The FWI system reflected the regional fire danger and could be effectively used there in wildfire management. The various FWIsystem components were classified into classes (i.e. low to extreme)for fire conditions found in the region.A total of 81.1%of the fires occurred in the high, very high and extreme fire danger classes, in which 73.9% of the fires occurred in the spring (0.1,9.5,33.3 and 33.1% in March, April, May and June). Large wildfires greater than 200ha in area (16.7% of the total) burnt 99.2% of the total burnt area. Lightning was the main ignition source for 57.1% of the total fires. Result show that forest fires mainly occurred in deciduous coniferous forest (61.3%), grass(23.9%) anddeciduous broadleavedforest (8.0%). Abimodal fire seasonwasdetected, with peaks in May and October. The components of FWI system were good indicators of fire danger in the Daxing'anling region ofChina and could be used to build a working fire danger rating system for the region.
